ABSTRACT:
A geometric figure teaching aid includes a base, a rod affixed to and extending from the base, and a series of side members interconnected with the base and the rod. The base is preferably formed of a translucent material, and the rod is mounted to the base at a first end and terminates at a second end spaced above the base. The side members extend from edges defined by the base member and are engaged with the rod at the second end of the rod. Clips are mounted to the side members, and are adapted to receive labels for identifying characteristics of the geometric figure represented by the side member, or to carry a given value corresponding to a problem. Lines are provided on the base, extending from the center of the base, from which the rod extends, outwardly to locations at which the side members are engaged with the base. The lines correspond to dimensions or aspects of the geometric figure. The base is preferably formed of a translucent material defining a top surface and a bottom surface, and the lines are preferably formed on the bottom surface of the base. The top surface of the base can be written upon by an instructor, so as to apply indicia relevant to the aspects or dimensions represented by the lines on the base. The teaching aid thus enables an instructor to apply indicia identifying the various aspects of the geometric figure, or given values for a particular problem. In this manner, the various aspects of a geometric figure can be readily visualized and understood by a student, thus facilitating a student's learning of geometric figures.
